Just picked up a Voyageur yesterday for $40. It is in fairly good condition. Sorry, no pictures, but it is a going to be a nice bike when I get done with it.
It is set up for half step plus granny with 50/46/28 chainrings and a 5 speed freewheel. I'm debating whether to cold set it from 120 - 126 and put a 7 speed freewheel on it and put on a smaller middle chainring. I've never tried half step gearing so I really don't know how hard it would be to get used to that.
I am a little reluctant to try cold setting for the first time on a frame that I would really hate to screw up. I've got a couple frames of minimal value on hand such as a well-worn Raleigh Reliant and a poor quality Schwinn Varsity. How helpful would it be to practice first before attacking a good frame? How would different frame materials react to cold setting (i.e. straight gauge on the reliant vs. Tange Champion #2 Extra on the Voyageur)?
Perhaps what I should do is overhaul the bearings, change the cables and housing, put on some bar end shifters, new handlbars, etc. and not worry about the drivetrain in phase one of the build process. Then I could ride it with half step plus for awhile and see if I like that before deciding for sure.
